GLOW-LAMP-SOCKET HOLDER.

SPECIFICATION forming part of Letters Patent No. 789,735, dated May 16, 1905.

Application filed February 3, 1905. Serial No. 244,069.

To all whom it may concern.-

Be it known that I, HERMAN T. HOOHHAUSEN, of Brooklyn, Kings county, New York, have invented a new and useful Improvement in Glow-Lamp-Socket Holders, of which the following is a specification.

The invention relates to the holding of electric glow-lamps upon a plate or other support.

The invention consists in the construction of the lamp-socket and of the plate or support having an opening to receive said socket, as more particularly pointed out in the claims.

The object of the invention is to enable the lamp-socket to be readily attached to or detached from the holding-plate and to be locked in place thereon.

In the accompanying drawings, Figure l is a plan view of socket and plate from above or in front. Fig. 2 is a plan view of the same from below or behind. Fig. 3 is a side elevation. Fig. 4 is a plan-view of the holdingplate separately. Fig. 5 is a cross-section on the line m of Fig. 4.

Similar letters of reference indicate like parts.

The lamp-socketA is, as usual, substantially cylindrical or frusto-conical, is preferably of porcelain, and is provided with the usual internal-threaded metal lining B and also with the ordinary circuit connections 0.

On the rim of the socket are two oppositely-placed arc-shaped flanges D E. Extending from the outer periphery of the socket are two oppositely-placed arc-shaped projections F and G. The rim-flange D meets and overlaps the projection F at one end, as shown at H in Figs. 1 and 5, and similarly the rimflange E at its corresponding end meets and overlaps the flange G. The lengths of the arc-shaped flanges and projections measured on their outer peripheries are such that an interval I, Fig. 1, is left between the non-overlapping end of rim-flange E and the end of projection F, and a similar interval is left between the non-overlapping end of rim-flange D and the end of projection G.

The holding-plate J for the socket is preferably of thin metal and is provided with an opening K of suitable shape and size to receive the rim-flanges D E and to allow them to pass through until the projections F and G meet the back of the plate, as shown in Fig. 3.

The portions Land M of the plate J, which project into the opening K, Fig. 4:, have their ends N bent downwardly.

The socket is secured in the plate by rotating it on its axis, so that the rim-flanges D and E ride over the plate projections L M until the arc-shaped projections F G enter and fill the intervals 0 between said projections L M and are locked in said intervals by the turned-down ends N. These ends N prevent the socket rotating of itself in the opposite direction, and thus retain it in place. When it is desired to release the socket, it may be grasped by the hand and first drawn downward until through the resiliency of the plate the projections F G become disengaged from the ends N, and afterward it is rotated until the rim-flanges are in position to be removed through the intervals O.

I claim 1. The combination of a glow-lamp socket of substantially cylindrical form, having two oppositely-disposed rim-flanges and two arcshaped projections on its periphery respectively lapping said rim-flanges at one end, and a holding-plate for said sockethaving an opening constructed and shaped to permit said rimflanges to pass through it and to permit said socket to be rotated to bring said rim-flanges over the portions of said plate projecting within said opening, and the said arc-shaped projections into the spaces between said portions.

2. The combination of a glow-lamp socket of substantially cylindrical form having two oppositely-disposed rim-flanges and two areshaped projections on its periphery respectively lapping said rim-flanges at one end, and a holding-plate for said sockethaving an opening constructed with internal projections L, M, having depressed ends N: the said opening being constructed and arranged to permit said rim-flanges to pass through it and to permit said socket to be rotated to bring said rim-flanges over the plate projections L, M; and the arc-shaped peripheral projections into the spaces O between the depressed ends N of said projections L, M.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

HERMAN T. HOOHHAUSEN.
